Aave Faces Potential Losses of Up to $230 Million Following Kelp DAO Bridge Exploit

A recent exploit of the Kelp DAO and LayerZero bridge has put lending protocol Aave at risk of losing up to $230 million. The incident, which occurred over the weekend, involves rsETH, a liquid restaking token issued by KelpDAO. The protocol uses a bridge mechanism to transfer rsETH between blockchains, but an attacker exploited this setup by creating a fake transfer message, effectively creating new tokens without backing. The attacker then deposited these tokens into Aave as collateral and borrowed approximately $190 million in ETH and related assets. Aave has taken steps to contain the risk, including freezing rsETH markets and halting new borrowing. However, the outcome depends on how Kelp handles the shortfall, with potential losses ranging from $124 million to $230 million. The exploit has raised concerns about the security of interconnected DeFi infrastructure and the potential for undercollateralized loans.
